Me: So how old are you?
Sophia: Three.
Me: Yes, you are. How old am I?
Sophia: I don't know.
Me: I'm forty-two.
Sophia: Noooooo!
Me: Yes, I'm forty-two years old.
Sophia: Nooo.
Me: Why not?
Sophia: Because that's a really big number. Mommy has a big number, but you have a bigger number!
Me: You're right. You're just one, two, three years old, and I'm....(I proceed to count really fast to forty-two)...years old!
Sophia: Hahaha! Do that again!...
(It's cute that she gets pleasure from my big number more than I do ; )
"The Answer to the Great Question... Of Life, the Universe and Everything... Is... Forty-two, said Deep Thought, with infinite majesty and calm."
